Directly managed public houses can be simply understood as state-owned houses and collectively owned houses. You can't buy or sell public houses directly. They need to go through certain procedures and need SASAC's approval before they can go through the handover procedures. The transaction forms of the right to use the house include: the lessee of the public house exchanges the right to use the public house by making up the difference; The lessee of public housing transfers the right to use public housing with compensation; Tenants of public houses exchange property rights with the right to use public houses; The lessee sublets part or all of the rented public houses to others for use. After the exchange of the right to use public houses, the paid transfer and the exchange of housing property rights, the property rights of public houses remain unchanged, and the new lessee shall re-sign the lease contract with the lessor.
